You have absolutely no idea about Maradona. Back then the drugs and other off-field issues took away his focus and he became a shallow shelf at Sevilla.
Maradona is a player who could dribble at speed, without speed, tons of tricks in his locker, excellent passing and vision, shooter, ball control, technique etc. His mentality to win is another trait. It is no coincidence that Argentina flourished when Maradona was at his peak, with a team that was less established than the current Argentina squad. It was like a defensively sound team aided by the attacking genius of Maradona. The only problem with Maradona was that he can be very aggressive and of course, his off-field issues.
